Jeongjoksan is a mountain hike, so it's not a good rainy-day choice — trails and historic sites here are outdoors.

• Outdoor mountain attraction at 220m elevation, classified as a tourist site (관광지).
• Main features (Samnangseong fortress, archive ruins, summit trail) are all open-air.
• Suggested hike from behind Jeondeungsa Temple takes about 2 hours one way.
• Open year-round with no closing days, but no covered or indoor facilities are listed.
• Parking is available on site (operating.parking_available: true).
• No rain_safe or indoor_outdoor attributes are recorded in the data.

Based on place_type (attraction), short_summary_ko (mountain hike, fortress, outdoor sites), operating.open_hours_raw, and operating.parking_available. experience_attributes.indoor_outdoor and rain_safe are both null, so the rainy-day judgment relies on the place type and summary description.
